Riot, if you're going to make it so you can report an offensive or inappropriate summoner name, you need to add this feature to club tags, too. "KKK" is offensive, and has no place in League of Legends, the same goes for someone whose summoner name would be ki11.all.%%%z; - they're both inappropriate, but only one is able to be voted out of the game. (see, I can't even type f-g without it being censored)
Those who will quote the First Amendment, I suggest you brush up again on what the First Amendment is, what it means, and what it applies to.
Seriously, Riot, take this club name out of the game. It's really inappropriate and I can't believe you'd consider keeping it.
